| Aug 2, 2018 at 15:42 | comment | added | R. van Dobben de Bruyn | @ChrisWuthrich: non-reducedness is at the essence of inseparable morphisms: the fibres are not geometrically reduced. But somehow they glue together into a total space that is reduced. Such is life in characteristic $p$. | |
| Aug 1, 2018 at 13:48 | comment | added | Chris Wuthrich | What bothers me a bit with this picture is that it looks like $Y$ is not reduced, when it should be about the morphism being "strange" instead. Not that I have any better idea, though. | |
